HARRY ADOLPH FRIBERG, OF WEST SOMERVILLE, MASSACHUSETTS.

HINGE.

Application filed November 27, 1915.

To all whom it may concern Be it known that I, HARRY A. FRIBE'RG, a citizen of the United States, residing at \Vest Somerville, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Hinges, of which the following is a specification.

The present invention has relation to hinges, more particularly that class therein known as door hinges.

The object of the invention is the provision of a hinge of the above stated character wherein means are employed for permitting of the separation of the hinge plates, whereby the door to which the hinge is attached may be readily detached from its casing without the employment of a tool in the form of a screw driver and the like.

A further object of the invention is the provision of means for interlocking the hinge plates together, including pivotal keepers automatically retained in the removable leaf of the hinge, to prevent any w accidental separation of the plates upon swinging action of the door.

For a full. understanding of the invention and the merits thereof and also to acquire a knowledge of details of construction and the means for eflecting the result, reference is had to the following description and accompanying drawings, in which:

Figure 1 is an elevation of the hinge in assembled position; Fig. 2 is a perspective view of the rigid plate constituting the hinge, clearly illustrating its pivotal features; Fig. 3 is a vertical sectional view of the removable plate constituting the hinge; Fig. at is a longitudinal section taken through the hinge, illustrating the manner of connecting the plates together; and Fig. 5 is a plan view of the detachable plate.

Referring more particularly to the drawing by way of reference characters 5 denotes the hinge which in this particular instance is constructed of metal and the like and comprises-a rigid plate 6 and a detachable plate 7. The plate 6 is adapted for attachment to a door casing and the like through the medium of screws 8, while the plate 7 is adapted for connection with a door and the like through the medium of the fasteners 9. A connecting member 10 is employed for-detachably connecting the plate 7 with the plate 6, and is hingedly connected with the longitudinal plate through the medium Specification of Letters Patent.

of the pintle pin 11, passing through the overlapped bearings 12 and 13 of the hinge and the connecting member respectively. Encircling the pintle pin 11 is a coiled spring 14 adapted for automatically closing the door. I use in connection with the coiled spring let, a means which will prevent the breakage of the spring when the door is being taken oil of its hinges, and such means comprises a radially extending hook 1a carried by the upwardmost bearing 12 adapted to receive a loop 15, the latter being carried by the angularly extending upper end 16 of said spring. The connecting member 10 in this particular instance comprises a spring tensioned post 15 of substantially rectangular form in cross section and provided at its outermost longitudinal side edge with a pair of spaced parallel projections 16 extending outwardly and at right angles to the post, the extensions being formed with a reduced apertured end 17, presenting an inner concaved edge 18 and an outer convexed edge 19. The reduced ends of the said extensions 16 have pivotallyconnected thereto keepers 20, which are formed at their innermost end with a reduced portion 21 adapted to overlap and be pivotally connectedto the reduced portions 17 of the extension 16, through the medium of a pivotal pin 22. This reduced end 21 of the keeper presents an inner concaved face 23 and an outer convexed edge 24, whereby upon engagement with the respective concaved and convexed edges of the extensions, permit of a lateral swinging movement of the keepers in opposite directions.

The detachable plate 7 constituting the hinge, embodies a body portion 25 and a cover plate 26. The body portion of the movable hinge plate 7 is cut out as at 27 to provide a pair of horizontally disposed recesses 28 separated from one another by means of the integral partition wall 29. This partition wall is reduced at one terminal and throughout a portion of its length to provide a substantially key-stoneshaped extension 30 presenting grooved shoulders 31. Connected to the free end of the key-stone-shaped extension 30 and in straddling relation therewith, by means of a fastener 32, is a locking spring 33 of substantially W-shaped configuration having outer yieldable diverging limbs 31 adapted to extend within the recesses and in the path of movement of the keepers 20, the purpose v of which will be hereinafter clearly pointed out. These recesses 28 are closed at their outer sides by means of the cover plate 26 as clearly shown. It will therefore be understood that when it is desired to attach a door to its casing, the keepersare inserted through the recesses 28 of the removable plate, compressing yieldable limbs 34 of the spring 33, until the hooked ends 35 have cleared the walls 36 of the recesses, then through the action of the spring 33, the keepers are moved outwardly, thereby looking the hooked ends of the keepers in engagement with the movable plate 27 and preventing any accidental displacement of the movable plate 7 from the rigid plate 6, upon the swinging action of the door. Now, when it is desired to detach the door from its casing, without the employment of a tool in the form of a screw driver and the like, the hooked ends 35 of the keepers are grasped. and moved inwardly against the tension of the spring 33, to clear their engagement with the movable plate 7, which will permit of a free sliding movement of the keepers through the recesses 28, and permit of the detachment-of the door from the casing. It is further tobe stated that the connecting portion 37 ofthe spring 33 is seated within the grooves 31 of the partition member 29,

and preventing any accidental movement of the'limbs 34 from the path of travel of the keepers 20.

' From the foregoing description, taken in connection with the accompanying drawin the advantages of construction and of the method of operation will be readily apparent to those skilled in the art to which the invention relates, and while I have described the principles of operation of the device together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown ism'erely illustrative and that such advantages may be made when desired as are within the scope of the claims appended thereto.

Having thus described the invention, what is claimed as new, is:

1. A hinge embodying a pair of plates, one of said plates being formed with a pair of separated recesses, means for detachably connecting said plates together, said means embodying a pair of spaced parallel extensions adapted to slidably engage with the recesses of the latter mentioned plate, and means pivotally connected with each of the extensions for locking the first mentioned. means to the latter mentioned plate.

2. A hinge embodying a pair of plates,

one of said plates being formed with a partition, providing the plate with a pair of spaced recesses, means for detachably connecting said plates together, said means embodying a pair of spaced parallel extensions adapted to be slidably mounted within the recesses of the plate, and spring pressed means pivotally connected with the extremity of each extension for locking the first mentioned means to the latter mentioned plate.

3. A hinge embodying a pair of plates, one of said plates being formed with a partition, providing the plate with a pair of spaced recesses, means for detachably connecting said plates together, said means embodying a pair of spaced parallel extensions adapted to be slidably mounted within the recesses of the plate, means pivotally connected to the extensions for locking the first mentioned means, and means carried by the partition for holding the last mentioned means in locking engagement.

4. A hinge embodying a pair of plates, one of said plates being provided with a partition wall formed at its free end with a keystone shaped extension, the partition wall forming its plate with a pair of separated recesses, means for connecting the plates together embodying a pair of pivotally connected members, and a spring mounted upon the key-stone shaped extension of the partition wall for moving the pivotally connected members in looking engagement with the last mentioned plate.

5. A hinge embodying a pair of plates, one of said plates being provided with a partition formed with an extension presenting grooved shoulders, means for detachably connecting said plates together embodying a pair of pivotally connected members, and a springconnected with the extension of the partition wall and mounted within the grooved shoulders thereof for forcing the pivotally mounted members in looking engagement with the last mentioned plate.

6. A hinge embodying a pair of plates, one of said plates being provided with a partition formed with an extension presenting grooved shoulders, means for detachably connecting said plates together embodying a pair of pivotally connected hook members for engagement with the last mentioned plate.

In testimony whereof I affix my signature in presence of two witnesses.
